• if you are allergic to ergocalciferol (vitamin D) or any of the other ingredients of this medicine (listed in section 6)

Talk to your doctor or nurse before being given Ergocalciferol:

• if you have heart disease, problems with your kidneys or with your circulation
• if you have kidney stones
• if you have low levels of parathyroid hormone (PTH)
• if you already have high levels of vitamin D in your blood or if you are especially sensitive to vitamin D.

It is important that you are taking enough calcium in your diet so that your body can respond properly to your medicine

Tell your doctor if you are taking, have recently taken or might take any other medicines.

• Medicines for heart disease such as digoxin or verapamil as these can cause high levels of calcium in the blood leading to an irregular or fast heart beat.
• Antacids containing magnesium for indigestion. If you are on kidney dialysis this can lead to high levels of magnesium in the blood which causes muscle weakness, low blood pressure, depression and coma.
• Thiazide diuretics (‘water tablets’) to relieve water retention such as bendroflumethiazide as these can lead to high levels of calcium if your body does not produce enough parathyroid hormone (PTH).
• Phenytoin, carbamazepine, primidone or phenobarbital used for the treatment of epilepsy as these may cause ergocalciferol to be lost from the body too quickly.
• Any other medicine, including medicines obtained without a prescription.

If any of the above applies to you talk to your doctor or nurse before being given Ergocalciferol.
